Map beyond 2D. Visualize data using 3D models, extrusions (building heights), depth, time (as a dimension), or an unconventional multivariate approach.
This 3D relief map combines a modern digital elevation model (DEM) of Asturias with an antique geological map published by the Instituto Geográfico Nacional (IGN, Spain) in the mid-20th century.
The map is inspired by the work of cartographer Sean Conway, who transforms vintage maps into realistic 3D visualizations showing terrain elevation and texture.
The goal was to recreate a similar illustrative style — blending topographic depth with the aesthetic of traditional printed maps — to highlight the geological complexity of northern Spain’s landscapes.
